In addition, by substituting the formula (32) into the formula (44), i.e. PB=BH+
P S =P B =nB H (46)
By substituting the formula (43) and PS cos θ into the formula (33), a formula can be obtained as following:
Then, by substituting the formula (47) into formula (45), the following formula is obtained:
